Getting StartedNI USB-6509 devices feature up to 96 bidirectional per-port static DIO lines. If you have not already installed your device, refer to the NI-DAQmx for USB Devices Getting Started Guide.

Before installing your DAQ device, you must install the software you plan to use with the device.

Installing SoftwareSoftware support for the NI USB-6509 for Windows is provided by NI-DAQmx.

The NI-DAQmx CD contains example programs that you can use to get started programming with the NI USB-6509. Refer to the NI-DAQmx for USB Devices Getting Started Guide, that shipped with your device and is also accessible from StartAll ProgramsNational InstrumentsNI-DAQ, for more information.

Note For information about non-Windows operating system support, refer to ni.com/info and enter rddqld.

Installing the HardwareThe NI-DAQmx for USB Devices Getting Started Guide contains non-software-specific information about how to install USB devices.

USB Cable Strain ReliefThe two strain relief options for your USB cable are as follows:

Cable Strain Relief Groove MethodPress the USB cable into one of the two grooves on the underside of the NI USB-6509. Choose the USB cable groove that matches your USB cable size, as shown in Figure 1.

Zip Tie MethodThread a zip tie through the zip tie bar on the underside of the NI USB-6509 and tighten around the USB cable, as shown in Figure 1.

Figure 1. USB Cable Strain Relief Options

Mounting the NI USB-6509You can use the NI USB-6509 on a desktop or mount it to a standard DIN rail or a panel.

Desktop UseYou can use the NI USB-6509 on a desktop. The NI USB-6509 has grooves on the underside that allow it to be stacked on top of other NI USB-6509 devices.

For secure desktop use, you can adhere the supplied rubber non-skid feet to the underside of the device, as shown in Figure 2.

Note Do not apply the rubber feet if you are panel mounting the NI USB-6509 or stacking multiple NI USB-6509 devices.

Figure 2. Applying Rubber Feet to the NI USB-6509

DIN Rail MountingThe DIN rail mounting kit (part number 779689-01, not included in your NI USB-6509 kit) is an accessory you can use to mount the NI USB-6509 to a standard DIN rail.

Note Apply strain relief, as described in the USB Cable Strain Relief section, before mounting the NI USB-6509 to a DIN rail.

National Instruments Corporation 5 NI 6509 User Guide and Specifications

Panel MountingTo mount the NI USB-6509 to a board or panel, complete the following steps while referring to Figure 3.

Figure 3. Mounting the NI USB-6509 on a Panel

Notes Do not apply the rubber feet to the NI USB-6509 when panel mounting the device.

Apply strain relief, as described in the USB Cable Strain Relief section, before panel mounting the NI USB-6509.

1. Go to ni.com/info and enter the info code rd3233 to download and print the panel mounting template PDF.

2. Using the template, mark the bottom point and top point on the panel. The points will be 162 mm (6.375 in.) from each other.

3. Remove the USB cable from the connector on the NI USB-6509.

4. Screw a #8 or M4 screw into the bottom point on the panel.

5. Set the NI USB-6509 on the screw by fitting it into the bottom screw notch on the underside of the NI USB-6509.

6. Screw a #8 or M4 screw through the NI USB-6509 top screw hole into the panel.
